Semper Fit Basic Fitness Course Questions and answers
Newest RATED A+ 2025/2026 UPDATED
Define exercise physiology - CORRECT ANSWERS Exercise physiology is the science that
describes, explains, and uses the body's response and adaptation to exercise training to
maximum human physical potential.
It includes the interaction of the heart, lungs, and muscles, and how they respond to exercise.
Define optimal fitness - CORRECT ANSWERS Optimal fitness refers to the best functioning level
of fitness a Marine can attain. At the optimal level, the body of the Marine functions as
efficiently as it can.
Which factor measures a Marine's optimal fitness? - CORRECT ANSWERS Optimal fitness can
be measured by accomplishing missions without undue fatigue.
The ability of a muscle to contract repeatedly without fatiguing. - CORRECT ANSWERS
Muscular Endurance
The ability of the heart and lungs to work efficiently over an extended period of time and
provide oxygen to the working muscles. - CORRECT ANSWERS Cardiopulmonary Endurance
Refers to the muscular and fat make-up of the body. - CORRECT ANSWERS Body Composition
The ability to move your joints comfortably through a full range of motion. - CORRECT
ANSWERS Flexibility
The amount of force a muscle can produce. - CORRECT ANSWERS Muscular Strength
, Blood is pumped to the lungs by the (blank) side of the heart and pumped to the body by the
(blank) side of the heart. - CORRECT ANSWERS Right; Left
Identify six adaptations of the heart and blood vessels in response to exercise. - CORRECT
ANSWERS (1) The size of the heart increases making it able to pump more blood with more
force.
(2) The amount of blood the heart pumps with each contraction increases. This is due to a
combination of an increase in the heart size and a decrease in pulse that allows more blood to
enter the heart between beats.
(3) There is a decrease in the resting and training heart rate.
(4) The heart rate recovers to resting levels more rapidly after training has stopped.
(5) More capillaries form to supply the working muscles with oxygen rich blood.
(6) Blood pressure decreases.
Cpl Jones participates in endurance training 3 times per week while Cpl Jefferson participates
once a week. What effect may this have on both Marines' lungs. - CORRECT ANSWERS Cpl
Jones' body is effectively using a large amount of oxygen better than Cpl Jefferson.
The molecule that provides the energy for muscle contraction is? - CORRECT ANSWERS
adenosine tri-phosphate
Provides energy for endurance tasks - CORRECT ANSWERS Aerobic
, Provides energy for 30 to 90 seconds - CORRECT ANSWERS Anaerobic
Provides energy for 6 to 10 seconds - CORRECT ANSWERS Creatine Phosphate
Identify the three major benefits of warming up. - CORRECT ANSWERS (1) Increases body
temperature
(2) Improved range of motion
(3) Prepares the heart and lungs for higher intensity exercise
General Warm-up Method - CORRECT ANSWERS Increases Temperature
Improves Flexibility
Passive Warm-up Method - CORRECT ANSWERS Limited energy expenditure
Specific Warm-up Method - CORRECT ANSWERS Increases temperature
Incorporates activity specific skills
Allows for mental rehearsal
Improves flexibility
Identify two general guidelines to guide your warm-up - CORRECT ANSWERS (1) It should meet
the needs of the individual.
(2)It should be adaptable as the Marine becomes better conditioned.
